About Washed Activated Carbon
Our Washed and Acid-Washed Activated Carbon undergoes additional processing to remove impurities and reduce ash content below 3%. With neutral pH and ultra-low heavy metal content, it meets the strictest purity requirements.
Designed for pharmaceutical, food-grade, and electronics applications where conventional carbon's mineral content could compromise product quality.
- Ultra-low ash content below 3%
- Neutral pH for sensitive applications
- Reduced heavy metal content
- Suitable for pharmaceutical and food use

Why Source From Tanjin Carbon?
Direct factory supply, no middlemen. Consistent purity backed by ISO certification and rigorous quality control.
Ultra-Low Ash Content
Ash content below 3% ensures minimal impurities. Ideal for applications where metal contamination is unacceptable.
Neutral pH
pH range of 6-8 eliminates the risk of pH shifts in sensitive processes. No adjustment required before use.
Low Conductivity
Conductivity below 100 μS/cm makes our washed carbon suitable for electronics and high-purity water applications.
Heavy Metal Removal
Acid washing reduces heavy metal content to trace levels, meeting pharmaceutical and food-grade requirements.
Multiple Grades
Available in food-grade, pharmaceutical-grade, and electronics-grade specifications. Custom grades available.
Technical Support
Our specialists help you select the right grade and provide guidance on handling and storage requirements.
Frequently Asked Questions
Washed carbon undergoes additional acid and water washing to remove soluble minerals and reduce ash content to below 3%. Regular carbon typically has 5-8% ash content. Washed carbon is essential where purity is critical.
Acid-washed carbon is required for pharmaceutical manufacturing, food processing, electronics, and high-purity water applications where metal contamination or pH stability is critical.
We offer grades meeting FDA food-contact requirements, USP pharmaceutical standards, and electronics-grade specifications. Custom specifications available upon request.
Washing removes impurities but does not significantly reduce adsorption capacity. Iodine numbers of 900-1200 mg/g are maintained.
Standard MOQ is 500 kg for washed carbon. Smaller quantities available for testing. Contact us to discuss your requirements.
Store in sealed, moisture-proof containers in a clean environment. Washed carbon is more sensitive to contamination than regular grades. Handle with clean equipment only.
